A Natural Language-based Flight Searching System

When people search for flight ticket online, they interact with a web site by selecting the ticket information from a set of drop-down menus. This paper proposes a scheme that is more natural for people to interact with the flight ticket server. The scheme integrates a natural language interface with a flight ticket searching system. It allows the users to interact with the flight searching system using natural language. The system is based on the BERT model. Compared with the existing scheme, the proposed scheme achieves good accuracy.
